So I was browsing the web when all the sudden my foot was sprayed with hot liquid. I thought it was the puppy peeing on me, only to look down and see water dumping out of my computer onto my foot. I jumped up and pulled the cord for the for the comp.

The computer was EXTREMELY hot, the coolant as easily 90+F. A hose had blown off my motherboard VRM block. The whole thing was toasty, it was hard to disassemble as it was almost to hot to hold the components. Either the TMS stopped the fans or the pump. I have a coolant sensor and 4 temperature sensors though out my rig. One in the rad, one under the motherboard VRM, one on the CPU and one on my GPU block. All of them had 35C limits. I also had the pump powered by the TMS with a flow sensor.

I guess the board locked up or something. I got no warning, and no shutdown. Guess it gets to go in the junk bin and buy an aquaero.

Before buying any replacement parts also check the health of the pump. Pumps do have a finite life time and can fail. Fans can also fail, there was a batch I got (don't recall brand name) and if mounted vertically overtime the frames and blades would eventually stretch and cease the fan. There could be more at fault and it would be a pain to have the new controller arrive to find something else had also failed.
